Abstract

The invention discloses a TPMS apparatus with diagnosis and a control method. The method comprises steps that: A, a main controller activates a TPMS sensor through a TPMS wireless communication module, and correspondingly obtains monitoring information from the TPMS sensor; B, a communication connection is built between the main controller and an automotive electronic control unit (ECU) through a diagnosis communication interface, and the read sensor ID information is written in the automotive electronic control unit; and C, the automotive electronic control unit and the TPMS information are diagnosed and analyzed, and the automotive electronic control unit and fault codes in the TPMS are read and cleared and data flow information are obtained in accordance with the analysis results. The apparatus integrates TPMS detection, sensor replacement and match, and related electronic control unit diagnosis of vehicle TPMS, and meanwhile both hardware interfaces and software database support multi-car operation, thereby effectively solves problems of single and scattered function, and cumbersome usage of present various tire pressing tools, greatly improving work efficiency and reducing usage cost.

Description

technical field [0001] The invention belongs to the technical field of automobile tire pressure monitoring, and in particular relates to a TPMS device with diagnosis and a control method. Background technique [0002] TPMS (Tire Pressure Monitor System, Tire Pressure Monitoring System) is a set of detection system for real-time monitoring of tire pressure. Now commonly referred to as TMPS, it refers to a system for real-time monitoring of tire pressure, temperature, acceleration, etc. According to a survey conducted by SAE (Society of Automotive Engineers) in the United States in 2002, an average of 260,000 traffic accidents in the United States are caused by low tire pressure or leakage; and 70% of traffic accidents on highways 75% of tire failures each year are caused by tire leakage or insufficient inflation; while 46% of highway traffic accidents in China are caused by tire failures, of which only one of the tire blowouts accounts for 70% of the total number of accident...
